To all wlom it may concern-'1 Be it l::nown that 1, JAMES Bnxoouon, rcsiding at Niagara Falls, in the county of N'agara and State of New York, have invented certain new and useful In'iprovementS in Bool:-l t:-.;n1i11g Mechanism, ot which the following is a full, clear, and exact description, such as will enable others snilled in the art to which it appertains to make and use the same.

This invention relates to means for forming and handling sheets in the manufacture of sales books and the like. One of the objects thereof is to provide simple and etlicient mechanism for forming a set of leaves from a plurality of webs.

A more specific object is to provide mechanism of the above type for preparing and arranging a set of leaves of alternate single and folded form.

Other objects ill be in part obvious and in nart pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrai'igement of parts which ill be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the follhwing claims.

.in the acconuianying drawings, wherein is shown one of various possible cmbodiw ments of this invention,l igure l is it diagrammatic elevation thereof. Fig. 2 is a similar view of certain of the parts shown in .l ic'. 1 upon a larger scale and in more detailed form.

Similar referencecharacters refer to similar parts throughout both views of the drawings.

Referring now to Fig. 1 ol the drawings, there is shown a roll .1. which may be assumed to be of tissue paper, the web 2 from which passes over a tension roller 3 and suitable guide rollers =lto impression and plate cylinders 5 and (3 respectively. These cylinders are provided with the customary I Specification of Letters Patent.

From the rollers Sand 3 the web 2 passes through numbering, apparatus 8, which is herein diagrammatically represented and may he 01' any approved type. the specific construction thereof torming in itsef no 'part of the present invention. From the I BOOK-FOEMING MECHANISM.

numbering mechanism the web passes over rollers 9 to cutting cylinders 10, the action of which will hereinafter be described in detail. A sheet path 11 leads from cutting cylinders to feed rolls 12, as shown in the drawings. Also leading to feed rolls 12 is a web 13, which is suitably printed and numbered as by the mechanism ll, each con secutive portion of a length equal to that from the cutting point of the mechanism 10 to the bite of the rolls 12 receiving a numher and these numbers being repeated upon such consecutive portions, thus providing a portion bearing the same number twice of a length equal to twice that above set forth. From the rollers 12 the superimposed webs 2 and 13 pass toward the cylinders 15 and 16. It will be noted that inasmuch as at; each revolution of the mechanism 10 the web is severed it will be in the form of separate sheets as it passes toward the last'mentioned cylinders, and will preferablyrest upon the unsevered web l3,suitable tapes 21 being provided if desired.

The several parts are so proportioned and interconnected bysuitable gearing as to feed the web 2 at one-half the rate olt peripheral speed of the rollers 12, whereby upon its free edge entering the bite of the latter rollers it will be accelerated and spaced from the main portion of the web from which it is cut.

The cylinder-s15 and 16 are provided with cutting and creasing mechanism, which, as it is of a WLll-lUlOWlhtyPC, will not be described in detail. It is sutlicient to note that. upon the cylinder 16 are mounted two cutting blades 17 diametrically disposed upon the circumference thereof, and intermediate these parts are positioned the folding blades 18. lroper cooperating female parts are provided upon the cylinder 15, and it will be seen that the web 13 will be severed at each hall revolution of these cylindcrs Assuming the latter web with a sheet 1!) -l'roni web 2 superimposed thereon to enter between these cylinders, it is in'nnediately transfixed by carrying pins 20, the operation of which is well known, and carried partially about the cylinder. At a point substantially coincident with the end of sheet 1!), however, the creasing blade 18 engages the web .123 and creases the same, the folded portion being carried toward strippers 20, from which it passes into a suitable sheet path 21.

The operation of the above-described em bodiment of this invention is substantially as follows :Assuming a free edge of the web 2 to enter between the: rollers 12, it is instantly severed by the mechanism 10 and permitted to travel at the accelerated speed at which the rollers 12- are driven. This sheet having been suitably printed and nunn bered by the mechanisms (5 and 8 respectively. is thus superimposeduponthe web 13 and carried to a position between the cylinders 15 and 16. The parts are so synchronized as to sever the web 13 at a point substantially coincident with the forward free edge of the already severed sheet l9 and to translix the free erllges of both sheets as by the pins 20. These sheets are then carried partially about the roller lb and the creasing blade 18 brought into play at a point substantially opposite the rear edge of sheet 19,. The partially folded web 13 is thence carried about cylinder 15 until stripped therefrom at its folded portion by the parts 20 from which it passes into the sheet path 21. The succeeding cutting blade 17 thereupon severs web 13 at such a point as to bring the fold substantially midway between the ends of the severed sheet. There is thus passed into the sheet path 21 a folded sheet from the web 13 and an unfolded sheet 19 from the web 2 of substantially one-half the length thereof, thus providing an element for the completed boolr or pad comprisinga superimposed sheet of tissue paper predetermined length and a folded sheet or paper which is preferably of a heavier character and which in folded condition is of substantially the same length. It will also be apparent that the sheets it) are consecutively numbered and the sheets cut from web 13 are also consecutively numbered but bear this number twice, thus duplicating the same upon each portion of the leaf in its final form. These munbers are alilte upon lJ'Otll folded and single sheets, and upon being' rcnniived from the sheet path 2i as by a fly there is pro-- vided a pile of leaves of a form, disposi tion and character adapted to be bound into a well-known type of nninifolding book.

The entire series ofopcrations above set forth is repeated with each sheet, it being noted that on account of the rate of travel of the rollers 12 being double that of the feed of the web 2 the severed sheet l3 will, upon passing through these rollers, be spaced from the forward free edge of the web from which it is cutby a distance equal to onehalf the length of one sheet, thus insuring the arrival of this free edge at the rollers 12 coincident with the arrival at that point of the next succeeding section or portion of the web 13.

It will thus be seen that l. have providcd an efficient and reliable mechanism well adapted to accomplish the several objects of this invention. 1
